Error in OBS Studio

Issue:


OBS-studio installed from Repo fails to record or stream with NVidia GPU
enabled. The following error is thrown in the window

```
Failed to start recording
Failed to open NVENC codec: Generic error in an external library

Check your video drivers are up to date. Try closing other recording software
which might be using NVENC such as NVIDIA Shadowplay or Windows 10 Game DVR.
```

In the konsole, the following errors appear. 

```

I have the related codecs installed as the following came up when I ran "ffmpeg
-codecs | grep nvenc"

```

My issue is similar to what can be seen in this thread -
https://plus.diolinux.com.br/t/obs-studio-falha-ao-abrir-o-codec-nvenc-unknown-error-occurred/25340/19

Hence, I believe it is related to NVidia or the OBS studio build in the repo.
